This one is for an actual glass door or window, not a wood panel or screen. A professional glazier cuts a round hole into the pane and the frame seats into it, so the flap becomes a permanent part of the glass rather than something screwed onto a frame. It's built from UV-stable polycarbonate that holds up outdoors, with a 4-way manual lock and a brush weather seal on the self-closing flap. The flap opening fits cats and small dogs up to about 8kg (13lbs). Because it requires cutting into glass, plan on hiring a glazier for the install, this isn't a weekend DIY project like a panel-mounted flap.

| Install | Requires a hole cut into the glass pane, professional glazier recommended |
| Frame size | Approx. 30cm / 11.81in diameter |
| Max pet weight | About 8kg / 13lbs |
Can I install this myself?
The frame itself mounts with the included screws once the hole is cut, but cutting a round hole into a glass pane safely needs a glazier's tools. Budget for a professional install, not a DIY afternoon.
Why would I pick this over a screw-on cat flap?
If the door you're installing into is an actual glass pane, a screw-on flap for wood or thin panels won't seat or seal properly. This one is built specifically to be cut into glass.
How long does shipping take?
5-11 days from our supplier's warehouse, shipping cost included in the price.
